Customers are saying

Customers recognize the iO Series 9 Connected Rechargeable Electric Toothbrush for its exceptional cleaning capabilities, overall performance, and ease of use. Many appreciate the long battery life, useful app, convenient travel case, and helpful pressure sensor. However, some customers find the price to be high, and others have noted that the brush heads are different from the older Oral-B design.

This summary was generated by AI based on customer reviews.

The vast majority of our reviews come from verified purchases. Reviews from customers may include My Best Buy members, employees, and Tech Insider Network members (as tagged).

    Best toothbrush I've ever used. At any age, it's important to brush correctly. By using the phone app, you can see where you need extra brushing, you are scored every time you brush.

    It’s a great toothbrush you can’t go wrong with it. Probably, the only reason why I don’t like it as much is since, you if you touch the button below the power it you end up not only in a different brush but also, in another language. Lol.

    This toothbrush is one the Jetsons would use! Oral B app is what really makes it fun and interesting to use. Allows you to keep track of previous sessions, scores, enabling you to compete with yourself.

    Pretty great and fun to use, I would say one down side is the AI with the phone doesn’t match sometimes, I’m brushing a specific area and the phone will say I’m brushing something else.

    Great Toothbrush! The 3D guide in the app is terrific, although some of the time the app thinks the Toothbrush is brushing the wrong area.

    Times change, and I have advanced with Braun. This one has all the bells and whistles. The brush heads on this one really take care of business. You just adjust the motor to your cleaning strength.

    Worst purchase of the year. For the price, this isnt worth it. The app is ok. Does a decent job with tracking your brushing on each quadrant. But you have to hold the phone up to see the progres. Paired with how messy it is, using the app becomes not worth it. The battery dies mid brush, multiple times in a 2 minute session. Says its at 100% when starting a brush session but dies to 0% in 15-20 seconds. I’ll never buy one of these again.

    This is my first electric toothbrush and it did not disappoint. My teeth feel just like a professional cleaning after I brushed. Easy to use and comes with a travel charger. Highly recommend

    BestBuy Curbside Delivery is Terrible

    The product is good but the Service of BestBuy was terrible. I gave it 2 stars so you can read what is written below We went for the curb side pick-up at Reston, VA location. A store person was called and he said he will bring the item outside, it was 5:42 pm and the store closes at 6:30 pm. Stood outside for 45 minutes, no one showed up or picked up our call and we finally had to leave just to return the next day and pick-up the item. I understand it's not easy to become AMAZON but i am sure one can learn a trick or two. Next time you are forcing us to buy from AMAZON as these are not BestBuy exclusive products.

    The only way to fully benefit from this brush is to watch the app at the same time as brushing your teeth. the toothbrush still works without the app, but the benefits are from the app.
